Oh my GOSH!!! I am so scared now!!! I had my Mirena removed after 4 years in April. I had one period and now I'm pregnant! I'm very happy to be preggers (my fourth)! But I'm scared to death, too! I'm reading about Mirena crashes (hormone roller coaster I guess), possible birth defects to my baby...ACK!! I lost at least 6 lbs in the two months after removal without really altering my routine or diet, my emotions went haywire-but mostly around the time I got pregnant, I would have days of TIRED and then a day of WIRED (still do now that I'm expecting), no more IBS (THANK GOD!!)...so not all of the symptoms, but enough. Any advice?
